A man and woman were found dead in their Palos Park home Tuesday afternoon.
Mohawk Road was closed all afternoon and into the night as investigators work out the details of what transpired.
At 3:34 p.m. police received a call that a family member found a man and a woman unresponsive in their home, Chief Joe Miller said.
Emergency crews responded and both were pronounced dead at the scene, Miller said. Larisa Markewych, 55, and Walter Puk, 53 were pronounced dead, according to the Cook County Medical Examiner's Office.
Autopsies are being preformed Wednesday morning.
Police are not looking for a suspect.
"The incident was contained to the home," Miller said.
The large home at 12315 S. Mohawk Road home was rebuilt within the last several years, neighbors said. Police cars sit at each end of the block and yellow police tape stretches across the front of the property.
The South Suburban Major Crimes Task Force is handling the investigation, Miller said. The scene is still being processed and that portion of the investigation should conclude sometime Wednesday morning.
Updated 7:30 a.m. with the names of the deceased.
